Evaluation of PSP technique including dot peeling, subcision and intradermal injection of PRP in the treatment of atrophic post-acne scars.

BACKGROUND: Atrophic post-acne scars are common complications of acne. Many modalities are proposed, but each does not yield satisfactory clinical outcomes. To evaluate the therapeutic effect of PSP technique including dot peeling, subcision and intradermal injection of autologous platelet-rich plasma (PRP) for the treatment of atrophic post-acne scars.

PATIENTS AND METHODS: Twenty patients with different types of atrophic acne scars on the face were included. All patients received PSP technique in the form of dot peeling, then after 2 weeks, subcision and intradermal PRP injection were done simultaneously. PSP technique was performed for each patient every month for 3 months.

RESULTS: After 3 months of the last session, 30% of 20 patients had excellent improvement, 20% of patients had good improvement, 20% of patients had moderate improvement, and 30% of patients had mild improvement. There was statistically significant difference after treatment (p ≤ .001). Side effects were mild and tolerable and included erythema, ecchymosis, and hyperpigmentation. All types of scars showed significant improvement with no significant difference between them.

CONCLUSION: PSP technique was found to be a safe and cost-effective treatment option for atrophic acne scars.
